DOUGLAS COUNTY, Colo. — In the wake of Amendment 64′s passage, there has been some confusion about what is legal and what isn’t when it comes to marijuana possession, distribution and use.

The Douglas County Pattern Crime Unit (PCU) moved to clear up a little bit of that confusion this week, reminding a 22-year-old it’s still illegal to sell pot on Craigslist.

Perhaps believing that not setting a firm price might improve the permissibly of his actions, Andrew Kipling Walton posted an advertisement on the online marketplace suggesting he would trade marijuana for “donations,” according to PCU spokesperson Ron Hanavan.

In exchange for the 3.5 ounces of marijuana Walton gave them, two undercover PCU detectives donated a ride to the Douglas County Detentions Facility.

Hanavan said the detectives made contact with Walton using the email attached to his Craigslist advertisement, and made arrangements with him to deliver the marijuana to a location in Lone Tree.
